How to Install a New Power Steering Hose

Without the power steering hose, the power steering will not work, making turning the wheel very difficult. The power steering hose carries power steering fluid that allows the steering wheel to be turned effortlessly. Over time, the hose can rot or become damaged for various reasons, including inactivity, extreme hot or cold temperatures, and even debris. If you feel your steering wheel has become difficult to turn or it feels jerky, then the power steering hose may be damaged. Replacing a power steering hose can be accomplished at home, without a mechanic. The article that follows will explain how it is done.

Step 1 - Buy a New Hose

The power steering hose is an important hose in the vehicle. Purchasing one of these hoses is rather simple as they are fabricated for specific vehicles in mind. Go to the auto parts store with the make and model of your vehicle. The clerk at the store will be able to sell you the correct hose.

Step 2 - Identify the Power Steering Hose

Open the hood of your vehicle. Using the owner's manual, locate the steering box. It is usually located near the fender, on the left in the engine bay. It will have threaded fittings on each end. It will also be dark in color and braided unlike the other hoses which are solid black and smooth. This is a good time to snap a few pictures for reference when it’s time to put things back together.

Step 3 - Remove the Hose

Place the drain pan under this area to catch any power steering fluid that may pour from the hose. Locate the bolts that connect the power steering hose to the pump. Use the wrench and turn the nut toward the left to loosen it. It may be frozen by gunk and oil. Use a rag sprayed with degreaser to wipe down the nut and then try again. If it still will not budge; spray it with lubricant and try again. Pull the hose off the pump and then plug the hose with a rag. The other end of the hose is accessed under the left wheel well. Follow the hose to the other end removing clamps, bolts, and shields as you go. This end of the power steering hose will be removed the same way as the first.

Step 4 - Install the New Hose

Wipe down the valves the hose attaches to in order to remove oil and dirt. Place an end of the hose to the valve and tighten it with the wrench by turning it to the right. Repeat this process with the other end of the power steering hose and then tighten all of the clamps, shields, and bolts that you had to remove previously. Fill the power steering reservoir with power steering fluid until it reaches the “cold level.” Power on the vehicle and turn the wheel several times to bleed the power steering hose of air. While the car is running, look for leaks. If all is clear, fill the power steering reservoir. Replace the cap, close the hood and you're done.
